Abstract: with the development of high performance engineering plastics, plastic products industry, the industry needs to continue to grow, the injection molding process is more and more used in various performance requirements for manufacturing products. The quality of injection mold design, injection molding machine for the production efficiency directly affects the forming, quality and cost of products. The mold can be a very good injection molding millions of times, because of its long life, on the other hand, reduces the cost of molding and mold plastic parts, as a result, a good replacement, repair, so as to improve the production efficiency. In order to meet the growing needs of the industry and the quality of life needs, should continue to research and development, has been designed to improve the performance of the plastic injection mold, to meet the needs of all walks of life.

In this design, the cover plate, the design and development of CAD die comprises a convex, concave mold design, the ejection mechanism design, selection and optimization of injection machine, the design of gating system, cooling system design, mold and other work. In this design, designed to focus on forming the convex, concave die design, gating system, cooling system. The gating system is the soul of the mold design and cooling design, the design of gating system directly affects the plastic parts molding quality and production efficiency [1]. Therefore, the design of gating system of injection mold design is the key work. At the same time, the mold temperature has a direct impact on the quality of plastic parts and production efficiency, solidification time and shrinkage stress of die and mold temperature control of a direct impact, thus affecting the molding cycle of molds and plastic parts quality, and surface roughness. The size of the convex die size, focus on design and system structure design of gating system and cooling system. Through this design, we first learn to understand the situation and the current development situation, basic principle of injection mold and die design Chinese plastic mould structure and injection molding process.
